It can be a bit buggy at times, but when it comes to just playing music with the screen locked, it’s perfect.

Edit: I forgot to also mention that ad blocker extensions make sailing the seas on mobile much more manageable. Extentions, in general, have been a really nice addition.
You know Firefox for android does this natively. No plugin required.
That was my thought… I was thinking “I already do this without an extension”, so I had to verify that I wasn’t using an extension that I forgot about.
How? Mine does not as it is setup currently.
I play the video in Firefox then lock the screen, which stops the playback but then FF is in the media bar so I can press play to continue playback.
Didn’t realise that this worked, thanks!
